Active Recombinant Human CYP2C18 Protein

• Cat.No.: CYP2C18-29H
• Product Overview: Recombinant human CYP2C18 and human CYP-reductase without tag was coexpressed in Escherichia coli.
  Amount: 0.5 nmol cytochrome P450

Specification

• Species: Human
• Source: E.coli
• Description: This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum but its specific substrate has not yet been determined. The gene is located within a cluster of cytochrome P450 genes on chromosome 10q24. An additional gene, CYP2C17, was once thought to exist; however, CYP2C17 is now considered an artefact based on a chimera of CYP2C18 and CYP2C19. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
